3PE Exterior & Liquid Epoxy Coated
Interior Composite Steel Pipe
Product Introduction:
The 3PE Exterior & Liquid Epoxy Coated Interior Composite Steel Pipe for Water Supply is a type of composite pipeline that uses welded steel pipes—such as straight seam welded pipes, seamless pipes, or spiral welded pipes—as the base material. It features a three-layer polyethylene (3PE) anti-corrosion coating on the outside and a liquid epoxy resin coating on the inside. This pipe combines the excellent external protection of 3PE with the superior internal smoothness and hygienic performance of liquid epoxy, making it widely applicable in water supply systems.
Product Features:
- High Hygiene and Safety: The liquid epoxy resin meets national hygiene standards. Its smooth inner wall reduces scale formation and bacterial growth, making this composite steel pipe especially suitable for the transport of domestic drinking water.
- Strong Adhesion and Wear Resistance: The epoxy coating adheres firmly to the steel pipe substrate. During transportation, installation, and long-term use, the coating is resistant to peeling or flaking.
- Coating Uniformity and Applicability: The liquid epoxy application process allows for a highly uniform coating inside the steel pipe. It effectively covers complex internal structures such as elbows and tees, ensuring full protection of the entire internal surface. Liquid epoxy demonstrates better adhesion and curing performance on pipes with complex shapes.
Product Applications:
- Municipal Water Supply Projects: In municipal water pipeline upgrades and renovation projects, the corrosion resistance of the double-sided epoxy composite steel pipe helps reduce maintenance costs and improve water supply reliability.
- Industrial Water Supply Systems: In industrial processes—such as in the chemical, pharmaceutical, and electronics industries—strict water quality requirements often apply, along with potential exposure to specific chemical substances. This composite steel pipe can meet the demanding needs of industrial water supply and prevent corrosion caused by chemicals in industrial water.
